-1 14. oz can condensed milk (I used Eagle brand)
-1 1/2 cups water
-1 (4 serving) package of instant vanilla pudding
-2 cups French Vanilla cool whip

In a large bowl combine water and milk, add pudding and beat well. Let this chill for 5 minutes. Then fold in the cool whip. Layer pudding mixture with bananas and vanilla wafers. Chill and then grab a spoon!
